Allwinner Device Tree changes for 6.18

This tag contains two DT binding header changes that are shared with
the clk tree.

In this cycle we gained support for the MCU PRCM clock and reset
controller on the A523/A527/T527 family of SoCs, the NPU which is a
Vivante GC9000 IP block, and the NPU clock that was missing. The other
PRCM clock controller gained default bus clock rate settings. These
were not configured in the upstream U-boot bootloader, leading to them
running at slower rates. The assigned rates are from the user manual.

There is also a new board, the NetCube Systems Nagami SoM and two of
its carrier boards.

The A523 family development boards now have their internal RTC clocks
configured correctly, so that the RTC does not drift wildly. The missing
functions for the AXP717 on these boards are added. Missing reset GPIOs
and delays for Ethernet PHYs are added. Last, the Cubie A5E now has its
LEDs described and usable.

An overlay for the Orange Pi Zero interface (addon) board was added.
This can be used with the Orange Pi Zero and Zero Plus 2. Default audio
routing for these two boards (to be used with the addon) were added to
complement the overlay.
